CORRELATION BETWEEN CLIMATE EVENTS IN THE NORTH-ATLANTIC AND CHINA DURING LAST GLACIATION
EPISODES Of massive iceberg release (Heinrich events)(1-3) into the North Atlantic Ocean during the last glaciation were associated with recurring episodes of unusually cold North Atlantic surface water (Bond cycles)(4) and cold air temperatures over Greenland (Dansgaard-Oeschger events)(5,6).

EPISODES Of massive iceberg release (Heinrich events)(1-3) into the North Atlantic Ocean during the last glaciation were associated with recurring episodes of unusually cold North Atlantic surface water (Bond cycles)(4) and cold air temperatures over Greenland (Dansgaard-Oeschger events)(5,6). Four of the youngest of these cold events have also been reported in climate records from sites outside the North Atlantic region(7), but until now the entire suite has been identified only in North Atlantic marine sediments, Greenland ice-core records and, tentatively, in French lake sediments(8).
